Review on πŸ’» D-Link DSL-520B ADSL2+ Ethernet Modem by James Julien

Revainrating 5 out of 5

A good basic DSL modem with no fancy features.

Good basic DSL modem, without fancy features etc. Yes! Full text user interface! Lack of broken graphics (e.g. GIF/PNG/JPG) in the administration web interface. It's a bit tricky to set up at first as I keep entering the wrong password on the initial "Quick Setup" option. However, I have also noted below the three most important menu items that you need to know after the initial setup of this modem, including how to change the ISP login password and the menu to monitor service problems. My modem log says this modem model has a Broadcom BCM96345 chip, which Broadcom chips are said to be preferred for DSL modems. This modem says "Made in China", D-Link is headquartered in Taiwan. Regardless, this is the latest non-wireless DSL modem to hit the market alongside the older non-wireless TP-Link DSL modem. In addition, the manual contains provisions of the GPL/LGPL. (eg yes! Linux and open source!) Bought this to replace my apparently shorted TP-LINK TD-8816 DSL modem. TP-Link worked fine for 2-3 years until a phone repairman apparently checked the system. Shrug, so I just bought another non-WindStream modem! This is a good basic modem with no wireless features or attractive user interfaces. Very similar to the TP-LINK TD-8816 DSL modem, except there are no GIF/JPEG images in the web browser admin interface, which resulted in printing issues. This modem also offers a Telnet/SSH interface. A NOTICE. The three main menus in the modem's web administration interface are as follows: 1) Device Information > WAN: Shows whether you are connected to your ISP's network. For example, it shows your specified IP address. 2) Device Information > Statistics > WAN: Shows your SNR Headroom in dB, Attenuation in dB, Speed and Errors/Corrections. In other words, line integrity issues. Also includes information from the previous menu. 3) Advanced Setup > WAN > Edit to edit the username and password and add other DSL settings to login to your ISP. (e.g. UBER, QOS, PPPoA or PPPoE, LLC, login password, redial/retry method, MTU). strange reason. Logging is very minimal with the default settings, which is likely to provide very informative information when troubleshooting. If this is your only router/device between your computer and the phone line (e.g. no router), this device also provides a firewall and NAT. Particularities. If you've recently purchased a dedicated WiFi router or other router, those dedicated routers may work better than that modem's routing/firewall/NAT (etc.) capabilities, as dedicated hardware tends to work better than hardware with additional features . The great thing about these cheap modems is that if the phone repairman gets mad at you and decides to short your phone wiring to 48V by shorting out everything attached to the line, then this $50 modem will likely short out first and save the rest of that your network. (e.g. telephones, WLAN routers, etc.) from excessive voltage. Do that $50 repair/replacement scenario, not $150+, to replace wireless routers with an all-in-one DSL modem!

Pros
  • Firewall and Qos protection
Cons
  • Vulgarity
